Actually, I think that it should not.  I haven't tested it, though. 
The two packages are different and handled separately by rpm, so why
would it try to upgrade a different package?  There could be problems
if the two packages share some files, in which case they probably are
not meant to be used together.  Again, if you saw the FC3 perl upgrade
problem, this is what was going on there.

Yes, this is correct.  I have seen this several times.  If you want
only one of them, tell yum using the proper extension (.i386 or
.x86_64).  I would advise using yum to install packages over rpm as
the 32-bit packages in the x86_64 yum tree are the ones that are
"officially supported" (for lack of a better term).  The only
exception to this might be firefox.i386 if you want to run it
*instead* of the 64-bit version to use flash and/or java.
